Had the pink ='s last night. From my experiences usually the pink/red's are the same ones. Some call em pink, some call em red. If they are light red they are the same, if they are a dark red like the red A's that were around a bit ago were, then they are different and I can't comment on them.
If they are the light red ones, they are going to murder you man lol (of course tolerance and whatnot dependent). Everyone I was with took 1 and peaked HARD for like 3-4 hours and were feeling absolute bliss for about 8 hours+. Off of ONE.
They have a LOT of love in them though. I had to periodically sit down because it was just getting too much lol, but then after about 20 min or so of chilling I was ready to dance hard again and go in my own little world.
